WEATHER-STRIP.

To all whom it'may concern: Be it known that I ALFRED M. LANE, a

citizen of the United states, and a resident of the city of St. Louis and State of Missouri, have invented a new and useful Imfollowing is a specification.

My invention relates to weather strips,

cially adapted for use in connection with windows having swinging sashes, although a weather strip embodying my invention is not restricted in its application to windows of this particular type.

The prmclpal ob ect of myinvention is to provide a simple and efficient weather strip which will prevent water passing through or being blown through the space between the window and its frame. Further objects are to attain certain advantages which will be more fully set forth hereinafter.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter more fully set forth.

In the accompanymg drawing. which forms part of this specification, and in which like characters refer to like parts throughout the several views,

Figure 1 is a cross-section of a Weather strip embodyin my invention, showing it applied to the iottom of a easement window, the easement window frame and sash being shown in vertical section and the window being closed;

Fig. 2 is a view similar to Fig. 1, showing a modified form of construction.

In the construction which I have shown in Fig. l,' the weather strip comprises two cooperating members A and B. The member A is formed of a strip of resillent sheet metal which extends along the under face of the bottom rail 1 of the window sash in the rabbet 2. One marginal portion 3 of the member A is fastened by tacks 4 orother suitable fastening means to the bottom rail 1 at the outside or weather edge 3 is bent to form a flange 5, which extends Specification of Letters Patent. Application filed March at, 1914. Serial a... 826,009.

downward and forms a drip edge. The member A has a body portion (3 which is adjacent to the marginal portion 3 and arches downwardly away from the face of the rabbet 2. The member A thence bends downprovement in Weather Strips, of which the ward and backward toward the marginal portlon 3 to form a pocket 7 having a round 1 bottom. The marginal edge of the member particularly to that form which is spe-- A is curled upon' itself to form a head or roll 8. The roll 8 and the body portion 6 body portion 6; and the body portion 6 and the pocket 7 lie spaced away from the face of the rabbet 2.

The other member B of the weather strip is formed of relatively stiff metal and is preferably of extruded metal. The member B is substantially a trough in cross-section, and its inner portion or wall and bottom are fitted in the angle between the sill 9 and the stool 10 and are secured to saidsill and stool by screws 11 or other suitable fastening means. The outer portion or wall of the member B is flanged and rounded at its upper edge to form a drip edge 12. This upper edge extends above the lower face of the rabbet 2 into a second rabbet 13. At intervals along the bottom of the outer wall are holes 14 for draining water from the inside of the member B. The inner Wall of the member B has at itsupper edge-,substantially on a line with the top face of the stool 10, a horizontal portion 15 extending outward. At the outer edge of this horizontal portion 15 the inner wall curves upward and backward upon itself to form a groove 16 and a sealing tongue 17. The sealing tongue 17 is slightly curved and inclines upwardly from the groove 16. In the closed position of the window (as shown in Fig. 1) the sealing tongue 17 lies in the pocket 7 and the roll 8 in the groove 16.

The joint between the members A and B is characterized by three lines of contact between the members. The lips of the pocket 7 press tightly against both faces of the sealing tongue 17 and thus form two limited to the particular constructio lines of contact. The roll 8 fits tightly against the bottom of the groove 16 and forms the third line of contact.

The member B may be used with different in Fig. 1. The member G which cooperates with the member B is formed of a strip of resilient sheet metal which is reinforced by a sharp rebend 18 at one margin and fastened by tacks 19 or other suitablefastenin means to the under face of the bottom rall 20 of the window sash. Thebody portion 21 of the member C is arched downward away from the bottom face of the bottom rail 20. The other margin of the member. C is curled to form a head or roll 22. head '22 engages the groove 16.

The outer wall of the member B acts as a shield for the joint between the members A and B and protects this joint against the direct action of water, dust or other weather elements. Any water entering the space between the face of the rabbet 13 in the bottom rail 1 and the upper edge 12 of the outer wall of the member B will tend to flow down along the inside face of this outer wall or drop from the drip edge 5 of the member A. In case any water is forced over the drip edge 5, it will tend to follow the inside face of the inner wall rather than passthe line of contact between the arched portion 6 andthe sealing tongue 17. Any

building. The holes 14 drain off the water from the inside of the member B.
